FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No, 419,891, dated January21, 1890. Application led August 3l, 1889. Serial No. 322,527. (Nomodel.)

To a/ZZ whom t may concern:

Be it known that we, JOHN SCHADE and FRANK BELL CASE, citizens of theUnited States, and residents of Brooklyn, in the county of Kings andState of New York, have invented certain new and useful Improvements inSelf-Locking Sash-Fasteners; and we do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying.drawings, and to lettersof reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is atop view. Fig. 2 is a vertical section, and Figs. 3 and Il are details.

This invention relates to locks or fastenings for the meeting-rails ofwindow-sashes; and it consists in the novel construction and combinationof parts, as hereinafter described, and pointed out in the claims.

The obj ect of the invention is to provide a fastening for themeeting-rails of sashes which will baffle the efforts at lateral orvertical displacement of the same when made from the outside of thewindow, and at the same time to provide for the proper lateral andlongitudinal adjustment of the upper surfaces of the said meeting-railsand automatically lock the saine together when the sashes are operatedto close the window.

In the accompanying drawings, the letters A A indicate the meeting-railsof the upper and lower sashes of a window, having secured thereto,respectively, the latch-plate B and the catohrplate C. The lock orlatch-plate consists of a casting comprising a suitable horizontal baseh, perforated for attachment to the rail A, and a central prominence G,recessed to receive a horizontal transverse spring-actuated latch D,having a beveled end c, which projects from the edge of the bearing,the'remaining portion of the outer end of the latch below this bevel endportion normally standing about flush with the outer end of saidbearing, thus forming recess or notch fv. The forward part of thelatchplate Bis provided with a guard-swell E, pro-a j ecting from ltheedge below the overhanging end of the latch, having an internallybeveled or dovetailed concave recess H to receive the correspondingly-shaped catch projection CZ of the catch-plate O. Thecatch-plate C consists of a base port-ion having apertures forsecuring-screws land projecting from its middle portion horizontally theconvex dovetailed catch CZ. The shape of the catch d is that of asection of a truncated cone, and the recess H, which therewith completesthe lock, is of a corresponding concave form. The mutual adaptation ofthese meeting parts to each other tends to draw the sashes to a properrelative position in the window-frame.

When the parts are in position and secured to the sashes, thecatch-plate on the lower and the latch-plate on the upper sash, there'will be no obstruction to the ready movement of the sashes, raising orlowering the same, except when they are completely closed. In suchclosed position the catch projection having passed the beveled end n ofthe latch descends into the concave recess of the latchplate, and thelatch of said plate, actuated by its spring, shoots over the catchprojection to lock it down. The concave projection of the latch-plate,which receives the catch proj ection of the lower sash-plate, serves asa complete guard, concealing the catch projection, and, as it spans thecrevice between the meeting-rails of the sashes, preventing access tothe locking-latch through said crevice; also, it will be observed thatthe dovetail engagement of the catch projection and its seat in thelatch-plate secures the meeting-rails together, so that they cannot bepried apart without breaking the fastenings.

What I'claim, and desire to secure by Letters Patent, is-m l. Thesash-fastener consisting of the springpressed latch beveled at its outeror projecting end, the case or closure containing said latch, and thecatch-plate flared at one end and engaging a corresponding recess insaid case or closure, said recess underlying the projecting end of saidlatch, substantially as set forth.

2. The sash-fastener consisting of the springpressed latch having anouter projecting end beveled on its upper surface and a notch or recessbelow said end, the catch-plate having the catch of a section of atruncated cone in shape, and the case or closure containing said y Intestimony whereof We affix our signatures in the presence of twoWitnesses.v
